Navigating the Ethical Landscape of Data-Driven Policing: A New Framework Emerges

Published on 25 November 2023.

Introduction:

In an era where technology is transforming every aspect of our lives, it comes as no surprise that police departments are increasingly turning to machine learning to forecast and manage criminal activity. However, the use of historical data in these algorithms raises concerns about biased and discriminatory policing. A recent breakthrough by the Northwestern Center for Advancing Safety of Machine Intelligence (CASMI) aims to address these issues through a comprehensive ethical framework.

Predictive Policing Advances:

Duncan Purves and Ryan Jenkins, philosophy professors from the University of Florida and California Polytechnic State University, respectively, have unveiled a groundbreaking ethical framework for place-based algorithmic patrol management. This method involves the analysis of past crime data to predict areas with an elevated likelihood of criminal activity. The voluntary framework, developed over a four-year period, consists of 63 recommendations targeting developers, police departments, and community advocates.

A distinctive feature of the framework is its emphasis on community involvement. CASMI’s workshop, “Best Practices in Data-Driven Policing,” brought together a diverse group of stakeholders, including software developers, computer scientists, law enforcement, lawyers, and community advocacy groups. According to Kristian Hammond, director of CASMI, the goal is not just to bring stakeholders to the table but to empower and listen to them. The recommendations prioritize seeking input from community advocates, recognizing their concerns, and ensuring their voices are heard.

The Framework

Key Themes:

The framework addresses two main themes: mitigating bias in data sources and building community trust. Purves highlights the importance of careful selection of data sources, noting that a focus solely on crime data, especially arrest data, can still perpetuate biased outcomes. Jenkins emphasizes the framework’s goal to help police integrate algorithmic patrol management responsibly, fostering community trust in the process.

Transparency and Accountability:

Law enforcement agencies often do not disclose their use of algorithms for predicting crime. To build public trust, the framework recommends transparency in the development process, inclusion of ethical requirements in product specifications, and continuous evaluation of metrics related to bias, transparency, and explainability. The goal is to demystify these technologies and guide public conversations surrounding their use.

Implementation Challenges and Opportunities:

Implementing the framework involves a range of recommendations, from prioritizing transparency in development to hiring a chief ethics officer. While some recommendations are straightforward, others may pose financial challenges. However, the framework suggests that doing the right thing is often good business, with some tech companies already taking a stand on certain applications of their systems.

Looking Ahead

Researchers are actively engaging with a major developer of data-driven police technologies to test the framework’s recommendations. The aspiration is to contribute to positive outcomes for public safety and police-community relations, moving towards a more harmonious future. As the ethical landscape of data-driven policing evolves, this framework stands as a significant step in fostering responsible development and deployment of technology for the benefit of all.
